CLOSURE FOR BOTTLES, JARS, OR OTHER RECEPTACLES.

Specification of Letters Patent.

Application filed March 13, 1905. Serial No. 24:9,729.

To wZZ who/12, it 7II/(I/Z/ concern.-

Be it known that I, JOSEPH V. HULL, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Closures for Bottles, Jars, or other Receptacles, of which the following is a specification.

The invention relates to improvements in closures for bottles, jars, and other receptacles; and it consists in the novel features hereinafter described, and particularly pointed out in the claims.

The invention comprises a novel cap of sheet metal, having in its vertical Walls and above its lower edge a laterally-projecting annular beading, forming within it an annular groove holding a packing-ring, which, while readily passing downwardly upon the external sides of the bottle-head, may upon the special treatment of said bead hereinafter described have a portion of its body displaced into firm engagement with a shoulder provided upon said head, whereby the cap becomes securely locked in position upon the bottle and seals the same.

The invention made the subject of this application comprises certain improvements upon the closure described and claimedin Letters Patent of the United States, No. 770,751, granted September 27, 1904, and the said improvements pertain to certain novel structural features, enabling me to effectually utilize thecap for sealing bottles containing charged or gaseous liquids, my invention having to do with means for enabling the cap when in position to effectually resist the pressure exerted by the gases within the bottle.

in carrying out my invention 1 provide the lower edges of the annular heading of the cap with a downwardly-extending flange and construct said beading of such proportions that 1 may move its lower inner edges upwardly against the packing-ring and toward the upper inner edges of said beading without materially flattening the outer portions of said beading, whereby the outer annular portion of the packing-ring becomes held within a groove whose mouth is smaller than the outer portion of the groove, and the remaining portion of said packing-ring is squeezed laterally and downwardly below a shoulder on the bottle-neck and between said neck and the flange skirting the lower inner edge of said beading, the space between said flange and the adjacent Walls of the bottle-neck being greater than the space between the upper edge of said bead and the wall of said neck adjacent thereto, whereby the cap becomes securely locked upon the bottle-neck and effectually seals the same.

The invention will be fully understood from the detailed description hereinafter presented, reference being had to the accompanying drawings, in which Figure 1 is a central vertical section through the upper portion of a bottle-neck, having applied thereon the bottle-cap of my invention, the cap being shown in its initial condition prior to the treatment to which it is subjected in transforming it into an effectual seal or closure. Fig. 2 is a like view of same, illustrating the bottle-ca p after having been treated to lock it upon the bottle-neck and form the seal or closure. Fig. 3 is a horizontal section through the bottle neck and cap on the dotted line 3 3 of Fig. 1, a portion of the cap being removed to illustrate the packingring in the groove thereof; and Fig. 4 is a horizontal section through the bottle-neck on the dotted line 4: 4 of Fig. 2, a portion of the beading of the cap being broken away to indicate the packing-ring therein.

In the drawings, 10 indicates the bottle-cap, and 11 the neck, of a bottle for containing beer or other liquid or substance. The cap 10 will be formed of aluminium or other suitable sheet metal and has a top 12 and sides 11, in which is formed the annular beading 15, having the downwardly extending flange 16. The beading 15 extends outwardly from the general vertical side walls of the cap and forms within it an annular groove adapted to receive the packing-ring 17, which will be of rubber or other suitable yielding material. The cap will be utilized in connection with a bottle-neck 11, having a shoulder 18 to be engaged by the packing-ring 17, this shoulder preferably curving downwardly and inwardly from a point about the upper edge of the beading 15.

The cap 10 will be applied downwardly upon the bottle-neck in the manner illustrated in Fig. 1 and will then be transformed into the construction shown in Fig. 2, so that it may constitute an eflicient closure or sea] for the bottle. After the application of the cap upon the bottle-neck in the manner shown in Fig. l I move the outer portions of the beading downwardly and press the lower inner portions of said beading upwardly against the packing-ring and into reasonably near relation to the upper inner edges of said beading, as shown in Fig. 2, whereby the mouth of the beading becomes partly closed and pinches the packing-ring at about its middle portion, said packing-ring by the treatment to which the cap is subjected being compressed both outwardly and inwardly, the outer portion of the packing-ring being squeezed into the beading, which is then of somewhat pear shape in vertical cross-section, and the inner portion of the packing-ring being squeezed lirmly against the shoulder 18 on the bottleneck, with a portion of said packing-ring extended downwardly along said shoulder and between it and the flange 16 of the cap, as shown, whereby the cap becomes so securely locked upon the bottle-neck that it can only be removed upon the application of force, the cap thus constructed and secured being capable of resisting the internal pressure of gas within the bottle.

Il do not in constructing and applying the closure flatten the beading 15 in the manner represented in the aforesaid. Patent No. 770,751, but seek to pinch the packing-ring by moving one edge of the mouth of said beading toward the other edge thereof, whereby said mouth becomes of less width than the outer portion of the beading, with the result that the compressed portion of the packingring within the beading cannot be readily withdrawn therei.rom. The presence of the flange 16 at the lower edge of the beading 15 is of great advantage for two reasons, one being that a raw edge at the lower inner edge of the beading would cut into the packingring, a result which is avoided by providing the flange 16, against which the packing-ring may press instead of against a raw edge, and the second reason being that a part of the laterally-squeezed portion of the packing-ring becomes housed and compressed between the bottle-neck and the inner wall of the flange 16 and materially aids in looking the cap upon said neck. in the absence of the flange 1b the inner downwardly-extended portion of the packing represented in Fig. 2 would not specially be a locking medium, since it would lack the rigid backing afforded to it by said flange. The shoulder 18 on the bottle-neck curves inwardly and downwardly from about the upper edges of the beading 15, and with the use of a bottle-cap of the construction shown in Fig. 2 a substantial. surface of this shoulder is engaged by the packing-ring, which contacts with said shoulder from about the upper edge of said beading to a point adjacent to the lower edge of the flange 16.

\Vhat 1 claim as myinvention, and desire to secure by Letters Patent, is*

1. In combination with a bottle or other receptacle, a closure of the character hereinbefore described therefor, said closure comprising side walls having a laterally-proj eeting annular beading, a flange extending below said beading, and a packing-ring in the groove formed within said beading, said beading being reduced in a vertical direction along its mouth against said packing-ring so that the upper and lower walls of said beading lirmly bind against the upper and lower surfaces of said ring and hold squeezed from said groove a portion of said ring into firm contact with a portion of said bottle or other receptacle, for sealing the same and locking the closure in position; substantially as set forth.

2. In combination with a bottle or other receptacle having an inclined shoulder about its mouth, a closure of the character hereinbefore described therefor, said closure comprising side walls having a laterally-projecting annular beading, a flange extending below said beading, and a packing-ring in the groove formed within said beading, said beading being reduced in a vertical direction along its mouth against said packing-ring so that the upper and lower walls of said beading firmly bind against upper and lower surfaces of said ring and hold squeezed from said groove a portion of said ring into firm contact with said shoulder, for sealing the bottle and locking the closure in position; substantially as set forth.

3. In combination with a bottle or other receptacle, a closure of the character hereinbefore described therefor, said closure comprising side walls having a laterally-projeeting annular beading, a flange extending below said beading, and a packingring in the groove formed within said beading, the said beading along its mouth being pressed against said ring and firmly holding the outer portion of the same squeezed into said groove and the inner portion of same pressed against adjacent surfaces of the bottle-neck, said beading being of greater vertical diameter at its outer portion than at its mouth.
